Answer:
<h2>Gold</h2>
Explanation:
Assume Gold trait =P ,
Purple= p,
Given:
Gold (P) is dominant over purple(p), so P is dominant over p.
If the bear is homozygous pp ( recessive) then bear will look purple,
If the bear is heterozygous Pp, then bear will look gold,
If the bear is homozygous DD( dominant), then the bear will look GOLD,
